UNDERFRAME FOR CARS.

Specification of Letters Patent.

Patented Feb. 16, 1909.

Application filed January 14, 1908. Serial No. 410,795.

To all whom it may concern:

Be it known that I, Aivron BECKER, of Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful ln'iprovements in Underframes for Cars; and I do hereby declare the following to be a full, clear, and exact descri tion of the invention, such as will enab e others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in underfraines for cars,--the object of the invention being to provide an underframe for a short four-wheeled car of the caboose type and to construct such frame with a minimum number of parts without sacrificing strength and rigidity and still reducing to a minimum the cost of construction of such cars.

\Vith this object in view the invention consists in certain novel features of construction and their relative arrangement as hereinafter set forth and more particularly defined in the appended claims.

In the accompanying drawings, Figure 1 is a partial plan view of a car underframe embodying my improvements; Fig. 2 is a longitudinal sectional view of the structure shown in Fig. 1; Fig. 3 is a transverse sec tional view, taken on the lines mm and yy of Fig. l, and Fig. 4 is a detail view illustrating a slight modification.

1, 1, represent channelbeams which are disposed upon the pedestals of a car, and 2 represents a center girder comprising two parallel channeled members spaced apart by a suitable filler 3. The center girder isconnected with the supporting channels 1 by means of cross-beams 4. Each cross-beam 4 comprises two members and each of these members consists of a diaphragm provided at it edges with flanges and these flanged diaphragms may be made of either pressed or rolled steel. The vertical flanges at the inner ends of the respective members of each cross-beam is secured to the web of the adj acent center girder member, while the vertical flange at the outer end of each diaphragm is secured to the web of the adjacent supportin channel 1. A tension plate 5 extends rom one supporting channel 1 to the other and is riveted to the lower flanges of said channels and to the lower flanges of the center girder members, as well as to the flanges at the lower edges of the diaphragms composing the cross-beam members. A coverplate 6 extends over the center girder and the cross-beam members; is secured to the flanges of the cross-beam members and also to the upper flanges of the supporting channels 1 and the center girder 2, and at its ends said cover late projects over brackets 7 to the upper anges 8 of which it is riveted. The brackets 7, above referred to, have a general triangular form and in addition to the upper flange 8, each bracket is provided its lower diagonal edge with a flange 9 and at its inner vertical edge with a flange 10. The flange 10 of each bracket 7 is secured by means of suitable bolts or rivets to the web of the adjacent supporting member or channel 1. The brackets 7 serve as supports for the side-sills 11 and furring strips 12, similar in construction and size to the side-sills 11, are supported upon the crossbeams and one of these furring strips will preferably be located over each channel supporting beam 1.

The cross-beam at the center of the underframe may, if desired, be made of less de th than the others, as illustrated at 13 in F igs. 1 and 3. The construction however of this cross-beam is the same as that above described.

If desired each bracket 7 may be formed with an integral depressed seat 14: when it is deemed necessary in a particular case to employ a side-sill 15 of greater depth than the side-sill 11, shown in Fig. 3.

Having fully described my invention what I claim as new and desire to secure by Letters-Patent, is,

1. A car underframe comprising supporting channels adapted to be disposed upon the ear pedestals, a center girder, crossbearns, each of said cross-beams comprising two flanged diaphragms secured at their inner ends to the outer faces of the center girder and at their outer ends to the inner faces of the supporting channels, brackets secured to the outer faces of the supporting channels and projecting laterally therefrom in line with the cross-beams, and a cover plate extending over each cross-beam, the supporting channels, the adjacent brackets and the center girder and secured to the cross-beam members and said brackets.

2. The combination of center girder members, side supporting channels, cross-beams and fur-ring strips supported upon the tri- 11;

located between the center girder members angular brackets.

and the side supporting channels and se- In testimony whereof I have signed this cured to the side faces thereof, said side su specification in the presence of two subscribporting channels being in a position to fie ing Witnesses.
